She first appeared in contemporary sources in 1150, upon her marriage with Landgrave Louis II of Thuringia.

When in 1168 her husband reconciled with Henry the Lion, Judith began the construction of Runneburg Castle in Weißensee.

Judith survived both her husband and her eldest son Landgrave Louis III.

The inscription reads S. SOROR FRIDERICI INPERATORIS ("the sister of Emperor Frederick").

Due to the canopy, this grave stone was larger than those of the other Landgraves of Thuringia (which are also on display in the St. George church in Eisenach).
